About me

ABOUT

Enthusiastic engineer who loves blockchain, AI, automation, and poking around the internet.

I'm Rizaldy, an IT engineer with 5+ years across Web2 and Web3. I've run Solana validators at Edgevana, supported blockchain infrastructure at Chainstack, and shipped secure banking integrations at Bank Mandiri. These days I build my own products under Ksatria Corp, like RekberPay and TemanQRIS. What actually gets me out of bed is curiosity: taking apart how blockchains, AI systems, and automation pipelines work, then wiring them back together into something useful. If it can be automated, monitored, or reverse-engineered for fun, I'm already in.

Beyond the job titles, I help businesses solve real problems. On Upwork and with direct clients I've built websites, automated tedious workflows, integrated APIs and AI, and hardened systems against the stuff that keeps founders up at night. I care less about buzzwords and more about outcomes you can measure: faster processes, fewer incidents, and software that just works. Tell me the problem you're stuck on, and I'll figure out the shortest honest path to fixing it.
